The impact of breathing amplitude on dose homogeneity in intensity modulated proton therapy

Physics and Imaging in Radiation Oncology, 2017
Background/purpose: Intensity-modulated proton therapy (IMPT) dose distributions can be severely degraded in targets moving with respiration due to the interplay, range and blurring effects. In this study we investigated the joint and disentangled impact

Impact of heterogeneities on lateral penumbra in uniform scanning proton therapy [PDF]

, 2013
Purpose: In the treatment planning of uniform scanning proton therapy, an aperture block is designed for each beam with a margin, which typically includes the lateral penumbra measured in water (homogenous) medium.
